Parse a date and time in YYYYMMDD HH:MM[:SS][+-ZZZZ] format. Any
timezone will be ignored; the time is treated as local time. Fewer
digits are allowed, except in the timezone. The year may be omitted if
a default year has already been set.

Parse an account name. Account names may have single spaces inside
them, and are terminated by two or more spaces. They should have one or
more components of at least one character, separated by the account
separator char.
